How to Make a Simple Small and Strong Electromagnet
Okay ur electromagnet is ready now to test it take a converter of 800 850 ma i used 500 ma which is really weak and connect the pins using the alligator clips and then set the converter on 9v and above and u can test it by dropping a magnet inside it and it will stay in the middle and if ur using a 800 or 850 ma converter try keeping a iron or steel nail at the bottom of the
